I-IEEL-BREASTING MACHINE.

To all whom it may concern: I

Be it known that I, l VILLIAM H. APBEE, a citizen of the United States, residing at Marlboro, in the county of Middlesex, in the State of Massachusetts, have invented a certain new and useful Improvement 1n Heel- Breasting Machlnes, of which the following is a specification, reference being had to the.

accompanying drawings.

This lnvention relates to heelbreasting machines and more partlcularly to means for guiding the heel to be breasted under the cutter and afterward removing the breasting chip from the path of said cutter, the object of my invention being to provide suitable means to guide the heel into proper position under the cutter and, after the cutting operation remove the breasting chip.

With this and other objects in view, my invention consists in certain novel device's, combinations, and arrangements of parts, as will be hereinafter described and more specifically pointed out in the appended claims.

In the accompanying drawings, I have illustrated my improvement sufiicient to enable those skilled in the art to understand the construction and operation thereof.

Referring to the drawings, Figure 1 is a side view of certain of the parts of my heel breasting machine. Fig. 2 is an end view of Fig. 1, looking in the direction of the arrow a; same figure. In this view some of the parts are omitted and some broken away. Fig. 3 is a vertical section of the parts shown in Fig. 1. Some of the parts in this view are shown in a different position. Fig. 4 is a view corresponding to Fig. 3 but shows 7 some of the parts in a different position.

In the accompanying drawings, 10 is the base portion of the main frame having an upright bearing 11 in which is loosely mounted the shaft portion 12 of the cutterholder plate 13. A spring 14 encircles said shaft 12 and abuts, at one end, the bearing 11. The other end of the spring 14 has its bearingunder the flange portion 12 of the shaft 12. The spring 14 acts to retain the cutter-holder plate 13 in its uppermost position.

15 is the cutter and is preferably of curved contour. Said cutter is secured to the plate 13 by means of a screw 16. Secured to the inner side of the cutter 15 is a projection 17. Secured to the plate 13, by means of screw 18, is a member 19 having outwardly projecting arms 20. Adjustably secured in the V Specification of Letters Patent.

Application filed November 6, 1915. Serial N 0. 60,124.

outer ends of these arms are screws 21. Ad justably secured to the base portion 10 by screws 22 is a U shaped member 23. Se-

cured in the upwardly projecting portions of the member 23 are screws 24 upon which are loosely guided the outer ends of the bar 25, and said bar has adjustably secured therein guide screws 26. A spring 27 encircles each screw 24 and acts to retain the bar 25 in its lower position. Secured in the outer ends of the bar 25 are pins 28 each of which engages a slotted portion 29 of a lever 30. Each of said levers 30 is mounted on a stud 31, secured in the stand 32 which latter is secured to the member 23 with a screw 33. Secured in the member 23, by screws, 34, is a wood block 35 upon which the heel 36 to be breasted is placed.

- 37 s a guide plate adjustably secured to the member 23 by means of screws 38. By means of the guide plate 37 and the screws 26 the heel to be breasted is guided into the proper position with relation to the cutter 15.

I will briefly describe the operation of the above mechanism.

The heel 36. is first placed by the operator on the block 35 under, and in the path of, the cutting knife 15. The cutter is then forced downward into the heel 36, (Fig. 3) by means of a cam or other suitable mechanism (not shown), operating on the flange portion 12"" of the shaft 12. By means of the screws 21 engaging the lever 30, the bar 25 is raised at the time the cutter 15 engages the heel 36. As the cutter 15 is forced through the heel 36, the projection 17, secured to the inner side of the cutter, will force the breasting chip from the path of said cutter 15, (Fig. 4) discharging it through an opening in the base 10 and into a proper receptacle. After the operation is completed, the spring 14 will cause the cutter 15 to be raised to its upper or normal position. Screws 21 releasing the levers 30, the springs 27 will cause the bar 25 to return to its lower or normal position.

Having thus described my invention it will be evident many changes and modifications may be made therein by one skilled in the art without departing from the spirit and scope thereof, and I do not wish to be limited to the specific details herein disin combination, a reciprocating knife, means for reciprocating said knife, means for positioning a heel in the path of said knife including a member carried by said knife reciprocating means, depending members on said member; levers actuated by the latter, and a resiliently held heel gage, said gage being controlled to have vertical movement by the engagement of said depending members With said levers during the reciprocation of the knife, and means adjunctive of the knife for aiding the knife in the separation of the breasting chip from the heel.

2. In a heel-breasting machine, in combination, a reciprocating knife, means for reciprocating said knife, and means for positioning a heel in the path of said knife, including a member carried by the knife reciprocating means, adjustable screwthreaded members on said member, levers arranged to be engaged by said screwthreaded members, a vertically movable gage member for abutting the heel, and guide members having said gage member resiliently positioned thereon, said levers being arringed to control the movement of said gage member, as the knife reciprocating means is actuated, and means for moving said gage away from the heel as the knife engages the heel.

3. In a heel breasting machine, the combination With a reciprocating knife, of means for reciprocating said knife, means for positioning a heel in the path of said knife comprising a frame-like member having right angled outstanding arms, vertical threaded adjustable members on said arms said frame like member being carried by the knife reciprocating means, a vertically movable heel gage member, spring equipped upright guide members having said heel gage member resiliently mounted thereon, adjustable guide members on said heel gage member, and levers arranged to be engaged by said vertical threaded members, said levers being adapted to control the movement of said heel gage as the knife is reeiprocated, and means carried by the knife for aiding the knife in the separation of the breasting chip from the heel.
